How many times has it happened to you that you forgot to charge your mobile phone, or simply ran out of soufflé by the end of the day? At best, it’s an inconvenience, at worst, you may miss an important call or message, you may not be able to give your loved ones a vital sign, or you may not be able to pay by phone or validate a digital ticket. However, you don’t always have a portable battery bank or socket, adapter and cable to breathe life into your gadget.
Every phone is good as long as the battery is charged [+]
Although the main camera with a variable aperture and the design are the main emphasis of Huawei’s new flagship device, the operating time is also great thanks to the appropriate optimization of the Snapdragon 8+ Gen 1 and the EMUI 13 interface, as well as the 4700 mAh battery, which can be charged lightning fast at 66 watts – already if you have the adapter handy. If you still run out of energy while on the road, the Mate 50 Pro has a neat trick: it switches on at 1% charge. Emergency mode.
Lithium-ion batteries don’t take full discharge well, and devices don’t work when the voltage drops too much, so it’s better to avoid it for a long cycle life, and there’s been some extra power saving in the mobile market for some time that severely limits functions to prevent this. By the way, modern gadgets go before the complete discharge and turn off the phone with some energy reserve – if its use is vital, the remaining energy can be used without damage, and Huawei has made improvements in this direction.
On the one hand, the Mate 50 Pro’s Emergency mode offers a low-power main screen with a black background, where six application icons can be thrown. Not all of them support the mode, but most of them do, and in addition to the usual basic knowledge, starting the Petal Map or the Translator can come in handy if you want to find your way around a foreign place. With a 1% charge, the device provides three hours of standby time on the mobile network or 12 minutes of voice calls and quite a few QR code readings, as well as mobile payments, before the EMUI system safely turns off the phone.
On the other hand, the Mate 50 family uses so-called “energy storage pump technology” and, according to the press release, repolymerizes the remaining icons in the battery with a thin “suction straw” in order to collect some energy even at low voltage without shortening the battery life. Huawei does not detail the technology in any more detail than this, but it is more important that it really managed to extend the operating time a little after testing it live.
When it dropped to 1%, the Emergency mode was activated and it was actually possible to make phone calls with the Mate 50 Pro for a few minutes, and as soon as it was connected to the power source, the mode was turned off and the usual EMUI main page was loaded, so there was nothing for us to do. Of course, it is best to keep the charge systematically above 20%, with clever algorithms and hardware tricks, Huawei dances confidently even on the verge of discharge, reserving some extra operating time even for the last moment, which can be a life saver.
